DRAFT-RIGGING FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent lsTo. 402,581, dated May'7, 1889.

Application filed September 8, 1888. Serial No. 284,872. (No model.)

the draftrigging of railway-cars, and has for its object to so constructthe draft-rigging and combine it with the canbody as to make a riggingat the same time cheap, rigid, durable, and easily adjusted for anylength of draw-bar.

Reference being now had to the drawings which illustrate my invention,Figure lis a central longitudinal sectional elevation of mydraft-rigging applied to a railway-car; Fig. 2,

an end view on the section-1ine 0a or of Fig. 1; Fig. 3, a View on thesection-line y y of Fig. 1. Fig. 4 is a plan View of one of thedraftirons shown in elevation in Fig. 1, Figs. 5'

and 6 are respectively a side elevation and a plan view of one of thetwo buffer blocks or castings, and Figs. 7 and 8 are respectively a planview and an elevation of one of the key-blocks used in uniting thedraft-timbers with the center stringers.

A indicates the flooring of a railway-car; B, its end sill; C O, thecenter stringers; D, the

body-bolster; D, the king-bolt and castings whereby the body-bolsteris'united to a truck.

E is the coupling or draw-bar, 6 being a shoulder resting against onefollower, and e a key resting against a washer on the opposite follower.

F is the draw-bar stirrup; f f and h h, bolts uniting it, to the endsill and draft-timbers.

G G are bearing-rods; H, a solid block of timber framed in between thecenter stringers, and extending from the end sill, B, to a pointpreferably back of the body-bolster D. Heavy bolts h h, &c.,- are usedto secure the block H to the center stringers.

h and k are shoulders cut in the block H to secure the thrust of thebuffer-'castingsw I. is a chafingdron; J J, the draft-timbers, which arefirmly secured to the center stringers and end sill by bolts Z Z, L, ZZ, 0, and L,

the abutting faces of the timbers being cut away around bolt L, as shownat k, to admit the key-block K.

O O, &c., are cross-straps extending from one draft-timber to the other,and secured in place by the bolts which. unite them to the stringers. I

N N are draft-irons secured along the bottom of timbers J J, as shown.

at n are turned-up ends of the draft-iron, by which their hold on thetimbers is made secure; a n, recesses cut in the draft-irons to admitthe bottom edges of the buffer-blocks,

and n 11 &c., bolt-holes through which the bolts Z Z, &c., pass.

P P are the buffer-blocks, alike in all respects, P being anupwardly-extending shoulder, P its bottom edge, and P the openingthrough which the follower passes. The buffer-blocks are wider than thedistance be tween the draft-timbers, which have grooves cut in them toreceive the edges of the blocks.

R R are the followers; S, the openings between the followers; m m, &c.,bolts passing through the buffer-castings and the drafttimbers' tosecure them together, as shown, washer-plates M M being secured on theoutside of the timbers.

The draft-rigging is put together byinserting the buffer-castingsbetween the draft-timbers, so that their upwardly-extending shoulderswill rest respectively against the shoulders h and. 71 formed in blockH. (The position of these shoulders of the slots in the drafttimbers andof the draft-irons or of the slots n cut in them maybe varied at will tosuit different draw-bars. The shoulder h, for instance, may be againstthe end sill, B.) The edges of the buifer-castings rest in slots formedin the draft-timbers, and at their lower ends enter and rest against theslots at of draft-iron N. The bolts m are inserted and bind thedraft-timbers and buffers together in a .most secure and rigid manner.The followers and springs are then inserted and the draw-bar pin ispassed through them and keyed, as shown.

The great strength and rigidity of the construction described will be atone perceived. By the device of using the upwardly-extend ing shoulderof the buffer-castings in connection with the block H buffing shocks areto a great degree removed from the draft-timbers and distributed throughthe car, and even apart from this feature my construction is so strongand simple as to be exceedingly useful.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. I11 adraft-rigging, the combination,with the center stringers, of arailway-car with a block, H, framed between and bolted securely to saidstringers, draft-timbers J J, crossstraps O, and draft-irons N N, boltedfirmly together and to the center stringers, and butfer-blocks securedbetween the drafttimbers and bolted thereto.

2. 111 a draft-rigging, the combination, with the center stringers, of arailway-car with a block, H, framed between and bolted securely to saidstringers, draft-timbers J J, crossstraps O, and draft-irons N N, havingslots 91/ n bolted firmly together and t0 the center stringers, andbuffer blocks having their lower edges formed to enter slots 71 of thedraftirons secured between the draft-timbers and bolted thereto.

In a draft-rigging, the combination, with the center stringers, of arailway-car with a block, H, framed between and bolted securely to saidstringers, draft-timbers J J, crossstraps O, and draft-irons N N, boltedfirmly together and to the center stringers, and buffer-blocks P, havingupwardly extending shoulders P, formed to extend above and rest againstshoulders 71/ 71?, formed in block H, said blocks being secured betweenthe drafttimbers and bolted thereto.

4. In a draft-rigging, the combination, with the center stringers, of arailway-car with a block, ll, framed between and bolted securely to saidstringers, draft-timbers J J, crossstraps O, and draft-irons N N, havingslots at n bolted firmly together and to the center stringers, andbuffer-blocks P, having their lower edges, P formed to enter the slots nof the draft-irons, shoulders P', formed to extend above and restagainst shoulders h h, formed in block II, said blocks being securedbetween the draft-timbers and bolted thereto.
